Claims (Cl. 299-77 This invention relates to improvements in servicestation dispensing apparatus of the type in which the servicing hose isextensible from and retractible into a housing that contains theusualdispensing pump, meter and, register.

The extra hose, that enables extension of theservice range, may bestored inside the housing, as shown for example in Hope Patent No.2,242.749, dated May 20, ,1941, and acted on directly by a weight orother suitable retracting means. It is necessary to have the hose somounted that a portion of it may move into and outof the housing and maybepulled in various directions while outside the housing.

This invention is concerned with, andhas forits object, the provision ofimproved means for guiding the hose .during its passage out of and intothehousing and immediately adjacent thereto.

More particularly, the invention has for an object the provision of anarm, which is swivel led to one upstanding side Wall of the housing forswinging movement aboutahorizontal axis and is provided with apluralityof suitable guides for the hose. This arm, which normally hangsdownwardly when the hose ,is retracted, will be swung upwardly, when thehose is pulled toward the front or the "backof the housing, and guidethe hose around but out of contact with a corner of the housing.

The invention has for another object theconstruction of the swivelledguiding arm in two pivotally connected sections, each having a set ofguides, which sections will be relatively moved when the hose is pulledstraight outwardly from that side of the housingthrough which itpasses,in order to carry the two .setsof guides more nearly int-o alignment,thereby lessening the resistance to movement of thejhose and providingan easier pull and less wearonthe hose.

The invention will be disclosed with referenceto the illustrativeembodiment ofit in the accompanying drawings, in which:

Referring .to these drawings; Figs. 1 and 2 showaihousing .for the elementsof a service station apparatus such as is commonly used .fordispensing measured,quantities of .motor fuel and the like. This housinghas a base 1, side .walls 2 and 3 and front and rear walls 4 and -5,respectively, upstanding from the base, and a top wall 6. The front andrear walls 4 and 5 usually have ,windows, such as 7, through whichlheindications of .a register, located inside the housing, are visible. Thefluid is dispensed through a flexible hose 8 having on its outer end theusual valved dispensing nozzle 9, .which when not in use, rests on asuitable support 10with the delivery end of the nozzle disposed in a sQ-called ,boot .or shielding recess 11, provided in the side wall 3 of.the housing. Fluid maybe forced through the hose by any suitablepumping means and measured, if desired, by any suitable meterwhichdrives a suitable register, .all these elements usually being locatedwithin a housing such as that described. These elements are old and wellknown in the art and accordinglydescription and ,illustration of them isnot necessary to an understand- .ing of thepresentginvention.

This invention is concerned primarily with the guiding of the ,hose .-8,intoand outof the housing. The extra ,hose, that enables extension ofthe service range when desired, is stored inside the housing after thegeneral manner disclosed in the above-identified Hope patent. Theinnerend ofithehose 8 (,Fig. l) is attached to the depending end of a pipe12, ,which carries the pumped fluid. From pipe i 2, the ,hoseextendsdownwardly to and around a weighted sheeve 1.3 and thence upwardlytoward the top .of the housing where it passes laterally across thehousingover suitable guide rolls 14 and ,15 to and through an exit inthe side wall 3, such vexit being. provided through the swivelled end ofthe swing- .ing hose-guiding arm of this invention.

This swinging arm is preferably constructed .in two ,parts an inner.part lfi, which isswivelied atone end..to the side wall 3 of thehousing, and an outer. part 17, which is pivoted at its innerend to theouter end of the part 16. The ends. of these two parts are provided withsuitable guides for ,hose fi. As shown in Fig. 3, the inner end of arm16 has a hollow hub 18, rotatably engaged in a bearing sleeve 19 whichis fixed with its .axis horizontally disposed by means of bolts 20 thatclampa flange 21 on thesleeve towall 3. The bearing sleeve 19, as hereinshown, is lined with a nylon sleeve 22. The hub 18,has a flange 23 whichabuts flange 21. The flange 23 (Figs. 3 ,and @8) has projecting inwardlyfrom its inner face in angularlyrspaced. relation .three pairs of ears24. The .outer ends of the ears of .each pair. areinterconnected by anarc-shaped ,Wall 25. These ears .and walls extend inwardlybeyondthe hub18 as shown ;in-Fig. 3 and slightly beyond the inner end of bearingsleeve 19. The three walls 25 (Fig. 8) are rotatablyengagedwith thelining 22 of the bearing .19. .Each arc-shaped wall 25 is grooved andthese three .grooves (Fig. 3.) receive .a snap ring 26, which abuts .theinner end of bearing19 and holds:the arm 16 against axial displacementin its bearing. Extending between and :fixed atits endsin. each pair ofears 24 (Fig. 8) isa pin 27 which carries a roll 28 confined endwisebetween the ears. The hose '8 passes through the hollow hub of arm 16and between the three rolls 28 which form a guiding eye forthe hose.

The arm 16 extends outwardly and downwardly from the flange 23. This armhas two right-singularly turned side webs 29 (Fig. 2), which areparallel at the outer part of the arm and then curve outwardly as theyreach the flange 23 and merge therewith. A roll 30 is located betweenthe parallel parts of webs 29 and is supported by 3 a pin 31, mountednear its ends one in each such parallel parts and projecting therebyond.The outer arm 17 has at its inner end two parallel right-angularlyturned side ears 32 which receive between them (see Fig. 5) the parallelparts of webs 29 and which receive one in each the projecting ends ofpin 31, such ends being suitably fixed thereto. The arm 17 is thuspivotally connected to arm 16 for swinging movement about a horizontalaxis disposed at right angles to the axis about which arm 16 swivels.The swinging of arm 17 on pivot 31 is limited by stops 33 (Fig. 1) fixedone to the outer side of each web 29 near the outer end thereof. Theouter face of each stop 33 is normally engaged by parts 34 of the ears32 on arm 17 as shown in Figs. 1 and 3 but the arm 17 can swingcounterclockwise until lugs 35 on ears 32 engage one with each of theupper faces of stops 33 as shown in Fig. 7.

The lower end of arm 17 is divided into tWo branches 36 (Fig. 4) whichare initially parallel and then diverge outwardly. The parallel portionssupport between them a roll 37, which is mounted on a pin 38 suitablyfixed at its ends one in each of said portions. The outer and divergingend of each branch 36 has fixed thereto one end of a pin 39, whichcarries a roll 40, held against axial displacement by a snap ring 41,engaged in a groove in pin 39. The axes of the three rolls 38 and 39 aredisposed in triangular relation and these rolls form between them aguiding eye through which hose 8 extends. The axis of this guide is atright angles to the axis of the guide afforded by the three rolls 28 andnormally lies vertical or substantially so, as shown in Fig. 1. The hose8, when not in use, extends downwardly from the outer end of the outerarm 17 to a location near base 1 and thence upwardly with its nozzleresting on support 10, as shown in Fig. 1.

In use, the operator removes the nozzle 9 from support and carries it tothe tank of the automotive vehicle that is to be serviced. Depending onthe position of such vehicle with relation to the housing of thedispensing apparatus the hose will have to be pulled in variousdirections in order to reach the tank. In some cases it will benecessary to pull the hose sidewise toward the front wall or the rearwall of the housing and in such cases, the arms 16 and 17 will functionas one without relative movement about the axis of pin 31 and willsimply swing about the axis of the hollow hub of arm 16. The two guidingeyes afforded by the two sets of triangularly disposed rol'ls plus theintermediate roll 30 will guide the hose in a right angle bend of largeradius and enable the hose to be extended if necessary by a relativelyeasy pull on the hose. In other cases, it may also be necessary to drawthe hose around the front or back wall of the housing and in such cases,the two arms 16 and 17 will swing about the axis of the hub of arm 16without relative movement, into a position, such as shown in Fig. 6,where the hose can be brought around a corner of the housing withoutcontact therewith and thus with less frictional resistance to pulling onthe hose for outward extension, when desired, and without causingabrasion of the walls of the housing. Whenever the pull on the hose isdirected outwardly from side wall 3, the pull will swing arm 17outwardly and upwardly about the axis of pin 31 until the parts arepositioned as shown in Fig. 7. The axis of the two guiding eyes will bebrought more nearly into alignment, thereby enabling the hose to beextended with less effort and also with less wear.

The invention thus provides in a service station dispensing apparatus,of the type in which the servicing hose is extensible from the housingby a pull on the hose and retractible into the housing when the pull isreleased, an improved means for guiding the hose with respect to thehousing so that the hose may be freely pulled in any direction and sothat when it is pulled around a corner of the housing, it is maintainedout of contact with the housing to avoid abrasion thereof and alsolessen the resistance to pull on the hose.

What is claimed is:

1. In a fluid dispensing apparatus, having a housing with upstandingfront, rear and side walls and a top wall, a dispensing hose stored inpart within said housing and extending out of the same through one ofsaid side walls, a first hose-guiding arm having a tubular hub mountedon the last-named side wall near the upper end thereof for swingingmovement about an axis normal thereto and affording a first guiding eyethrough which the hose passes out of said casing, said first armextending outwardly from the last-named side wall terminating with itsouter end spaced therefrom and tending by its weight to hang downwardly,a second hose-guiding arm having its upper end pivoted to the outer endof the first arm for swinging movement about an axis parallel to thelast-named side wall and tending by its weight to hang downwardly fromthe outer end of the first arm, cooperating stops one on the first andone on the second arm for limiting the extent of swinging movement ofthe second arm toward the last-named side wall to a positionsubstantially parallel to and substantially spaced therefrom, and asecond hoseguiding eye on the lower end of the second arm, the hosepassing from the first eye to and through the second eye and thencedownwardly therefrom, said second eye encompassing the hose peripherallyto a suffioient extent to prevent the hose from being moved out of theeye in all directions radially of the latter, the axis of said secondeye being substantially parallel to the second arm, a pull on the hosein a direction outwardly from the lastnamed side wall causing the secondarm to swing outwardly therefrom and upwardly moving the second eye morenearly into alignment with the first eye, a pull on the hose towardeither the front or the rear wall swinging both said arms about the axisof the first eye and carrying the second eye outwardly toward either thefront or rear Wall and positioning it to guide the hose around and outof contact with the corner where the last-named side wall intersectseither the front or the rear wall.

2. The combination, as claimed in claim 1, in which a second pair ofstops is provided one on the first and one on the second arm to limitthe extent of outward swinging movement of the second arm relatively tothe first arm.

3. The combination, as claimed in claim 1, in which a guide roll for thehose is mounted on the pivotal connection between the first and secondarms.

4. The combination, as claimed in claim 1, in which each guiding eyecomprises a plurality of rolls angularly spaced about the hose andconfining it against movement out of the eye in all directions radiallythereof.

5. The combination, as claimed in claim 1, in which the axis of thetubular hub is located midway between the front and rear walls and theradial distance from the axis of the first eye to the second eye isapproximately equal to half the width of the last-named side wall.
